To all whom it may concer/n: 4

Be it known that I, JOSEPH W. SHARP, J r., a citizens of the United States, residing at Philadelphia, in the county of Philadelphia 5 and State of Pennsylvania, have invented new and useful Improvements in Water- Closets,rof which the following is a specification. l v

The present invention relates to water closets, and particularly to that type of closets known as vented cl osets,7 so called because provision is made forv venting the bowl by way of a suitable flue, ventilation giving also a Ventilating result in the room in which the closets are installed,

both bowl and room ventilation being secured by means of a suitable vent passage which leads from the bowl proper to the flue adjacent which the closet may be located.

It has for its obj ect to provide a bowl construction in which the venting passage lis conveniently and efficiently placed, so that its molding in the ware may be readily accomplished, and its efiiciency so far as venting results are concerned will be high; the arrangement being such thatflue connections may be conveniently made and at the same time flooding and fouling of the flue will be avoided.

In the embodiment of my invention herein shown I have illustrated various forms to show the different physical expressions of my invention, although it will be understood that the same principle underlies the several forms of the invention here exhibited.

In the drawings whichv accompany and form a part of this specification- Figure l is a sectional view of so much of a closet bowl as will illustrate my invention. A. Fig. 2 is a plan view of the closet shown in Fig. l, illustrating in dottedlines the arrangement of passages.

Figs. 3 and lare sectional views illustrating embodiments of my invention other than those ifound inthe .figures hereinbefore-referred to. A

Figs. 5, 6 .and 7 are sectional viewsy of bowls to illustrate other developments of my invention to which reference will be made in the detailed description which follows.

Referring now to the drawings by numerals, and irst to Fig. l, B indicates a bowl having any suitable supply Spud and Siphon passage, the supply Spud giving the necessary water to the bowl and rim by" the duct this bowl y "bowl,

fll and the contents make back into the yvent Hwardly,

b and rim passage b', both shown in dotted lines. 'Y

Traversing the upper portion of the bowl is a vent passage b2 which connects the bowl proper with a Suitable vent pipe b3 delivering to a suitable flue (not'shown) in the rear of the closet. The vent passage b2 islaid between the supply ducts b which lead from Athe Spud at the top of the bowl, and said vent passage passes over the top of the Siphon passage, as shown. l

The vent pipe b3 is shown in Fig. 1 as an independent pipe coupled by a suitable connection with the rear of the closet, a similar coupling lbeing provided at the rear end of said pipe b3 by which it is connected to the wall of the vent flue. Said vent pipe b3 has a slot or aperture b4 formed in its underside, which slot b* has the double function of providing direct ventilation from the room to the flue in addition to the ventilation which takes place through the bowl and vent pasy sage b2, thus preventing any flooding or fouling of the'flue in event of the choking of the for it is obvious that Should the bowl passage b2, the slot b4 in the vent pipe b3 would eectually drain to the floor and no contamination Of the flue could occur.

It will be observed that the slot b4 is located near the inner end of the pipe b3 so that a sufficient working length is left for the plumber at the outerend of the pipe to make such cutsand wall'connections as may be necessary in setting the closet without interfering with the vent slot bt.'

The vvent passage b4 of the closet lifts upas-Shown, and has a wall or dam bs (see Fig. l) which rises toV or above the level of the bowl rim, which dam bs while it does not interfere with the venting action guards against flooding the vent passages and the flue beca-use lof the fact that the. bowl contents will overflow. the bowl-,rim before they can pass thefdam bs, thus giving a safe guard additionallyto the slot 5"Y in the vent pipe b3 against flooding the vent passages and Hue. Y

In order that a proper wash of the vent passage and darn face may be given at each flush of the closet, I provide a connection from the spud atthe top of the closet, said connection comprising a chamber b5, which, when the flushing valve of the closet is pulled, receives water from the spud connection, and, by suitable apertures b delivers it directly upon the face of the dam be, insuring its frequent and complete cleansing.

Preferably I drop a web or apron 57 forward from the raised spud receiving portion of the closet, so that the receding aperture of Ithe vent passage '23 is to a considerable extent concealed.

The dam in the vent passage is formed by the upper Iwall vof -a refill chamber, as shown, which` refill chamber is located in the usual manner at the bend of the siphon passage and so formed as that its wall bs extends above the level of the bowl and eifectually dams the vent passage. u

Instead of forming the raised back, as shown in Fig. 1, namely, with a forwardly extending web, I may extend the chamber which receives its flushing water from the spud,supply forwardly, as shown in Fig. 3, so that a raised lstop is provided which gives a chamber C of sufficient capacity to properly flush the vent passage wall c, suitable apertures c being provided through which the wall-flushing jets may act.

In the form shown in Fig. el, the dam in the vent passage is formed by the upper wall of the refill box C, the upper wall of this refill box extending upwardly, as shown, into the vent passage, above the top of the bowl, the raised back ofthe bowl having the forwardly and downwardly extending web as shown, and being vprovided also with a washing chamber C2 which connects by a suitable orifice c2 with the supply spud, delivery orilices c3 being formed in the bottom ofthe chamberC so as to furnish a washing supply for the sloping face of the vent passage dam as it leads tothe bowl.

In Fig. 5, I have shown a raised back closet ink which the stop at the rear of the bowl is slightly different in form, said stop D having the vent passage Z passing through it with the forward end at an angleto the bowl rim shown, so as to present a good venting orifice to the bowl, the said passage Z passing rearwardly between the ductsV d v(see dotted lines) leading from the supply spud, and above a refill chamber d2, said `reliill chamber having the refill apertures d3, as shown. It will be seen that the top of the refill-chamber Z2 extends above the bowl rim, so as to dam the vent passage d effec- 'tually against iiooding.

In Fig. 6 a very similar construction to Ithat lfound in Fig. 5 is disclosed, except that the vent passage E passes below the refill chamber e, a raised dam e similar to those heretofore described being provided which will prevent back-flow from a choked bowl; said refill chamber e having apertures e2 which are so arranged vasto-wash the wall of the vent passage which slopes to the bowl and keep it in sanitary condition, and to supply wash for the rear of the bowl in lieu of the regular flush rim, which does not extend around the rear of the bowl.

In Fig. 7, I have shown the vent passage vdownwardly to the bowl.

In the forms ofmy invention heretofore described, I have shown the vent pipe which connects the closet `to the flue as formed of metal and coupled to the back of ythe closet, such pipe having the vent slot formed in it. I have shown in Fig. 7 how, by extending the ware of the closet back so 'as to give a neck I may form the vent slot f5 directly in the ware itself, the neck f4 being connected in any suitable manner to the vent ue.

'Ihe closet which I have invented and which is exemplified in the various forms disclosed, is one which may be readily molded in the vitreous ware now commonly in use; which will not flood back into the flue if the bowl chokes; and which will give always a proper ventilation of the bowl and room, not only through the bowl, but also through the direct venting slot of the flue connection.

Such variations yin design and structure as are but mechanical variations of my invention, I regard as within its range, and this disclosure is, therefore, to be regarded as restricted only in so far as it is restricted by the terms of the claims herewith.

I claim:

A water closet bowl having the usual supply and siphon passages :and provided with a Ventilating duct leading directly through the ware over the bend of the siphonpassage to the outside of the ware and having its inlet and outlet below the level of the bowl, an overflow preventing dam formed integrally with and projecting from the siphon bend toa point above thetop of the bowl, and means for flushing the dam.

2. A water closet 'bowl having the usual supply and siphon passages and provided with a Ventilating -duct leading through the ware over the bend of the siphon passage and directly out through the back of the ware,`said duct having its inlet and outlet' below `the level of the bowl, an overflow -preventing dam formed integrally with and projecting from the siphon bend above the top ofthe bowl, and a venting and draining aperture inthe wall of said duct on the outlet side of said dam.
